Alot of Cadillac Forums see this problem and recommend what they call the "Italian Tuneup" which is to take the car on the highway, then cram it into 2nd and full throttle. It may be effective for seating the rings, but I value my tranny and the cost to replace it. Try WOT through the gears a couple times. The engine will scream before it goes for 2nd, and a bit less to 3rd. But dont let off. The TCM knows when it has to shift.
I do this pretty much every time I drive the car at least 5 times. Not that I'm reckless, but I love the sound, and the feeling. I hear the only people with Northstars that actually have problems are the ones that baby their cars.
